CONTBOLLING DEVICE.

Application led August 3, 1923. Serial No. 655,461.

lvice particularly adapted for controlling valves and the like, and designed with a View of mounting the same upon the instrument board of an automobile or the like.

The construction of the invention lends itself particularly to an association of this character as yit includes a tubular portion` adapted to eritend through the instrument board of the vehicle and a headed portion by -which attachment to the instrument board may be accomplished.

The invention furthermore consists in the novel combination, construction and arrangement of parts, all of which will be made more apparent hereinafter as this description proceeds, especially when considered in connection with the accompanying drawings wherein;

Figure 1 is an elevational view of a device constructed in accordance with this invention;

Fig. 2 is a longitudinal sectional view, through the device;

Fig. 3 is a sectional view, taken substantially on the plane indicated by the line 3-3 in Fig. l;

Fig. et is a longitudinal view of a slightly modified form of construction; and,

Fig. 5 is an end elevation of the device.

Rewferrin now particularly to the drawings whereln like reference characters indicate like parts, it will be noted that the device consists of a tubular casing 10, having a headed portion 11, suitably apertured as at 12, whereby the device may be secured to the instrument board of a motor vehicle or the like.

The other end of the tubular casing 10 is provided with a cap 13, threaded thereon, this cap affording means for effecting connection with an easily bendable guide tube 14, adapted to guidingly accommodate an operating cable l5, preferably formed of spring wire, which extends to the valve or other device to be controlled.

Arranged in the casing 10 is an operating member 16, which, as shown in Fig. 2,`may

.have a corrugated exterior', or as illustrated at 16 in Fig. 4, may have aspirally threaded exterior. rlhe end of the operating member 16 in Fig. 2, which extendsl beyond the casing 10, is provided with a handle 17, whereby it may be manuallyoperated. 'lhe operating member 16 is connected to lthe wire 15, as indicated at 18 in Fig. 2, or it may be connected so that the handle 17 may be turned without turning the wire. lhis is accomplished, as illustrated in Fig. 4, by providing a head 19 on the end of the wire 15, this head engaging a tubular extension 20 secured to the end of the operating member 16 by means'of a pin 21.

In both forms of the device illustrated in Figs. 2 and 4, there is associated with the operating member 16 a pair of balls 22, normally urged into engagement with the operating members 16 or 16 by springs 23, housed in enlargements 241, formed on the hgad l1. The open'ends of these spring housings may be closed by plugs 25.

In the form of the device illustrated in Fig. 2, the handle 17 is actuated to pull the operating member 16 outwardly, the spring pressed balls 22 engaging the corrugations vformed in the operating member to maintain this member in any of its adjusted positions. In the construction shown in Fig. 4f the handle 17 is operated to axially displace the operating member 16 a short distance until the balls 22 engage the spiral thread, whereupon the operating member is further axially displaced by revolving the handle, as will be immediately apparent.

From the foregoing it will be obvious that there is provided a compact and conveniently operable controlling device which may be employed for any of the purposes hereinbefore mentioned, and in which the control may be easily effected and the device secured in any of its adjusted positions.

The construction of the device is such as to make it easily attachable, and its appearance is such as not to make it conspicuously unattractive.

While one embodiment of the invention, together with a slight modiication thereof, have been illustrated herein in some detail, it is not intended to unnecessarily limit `the invention, but reservation is made to make such changes as may come within the purview of the accompanying claims.

Having thus described the invention, what is claimed is:

1. In a control device of the class described, a tubular casing; a cylindrical operating member provided with a helical groove slidably mounted Within said casing, yielding detent members carried b said casing for engaging said groove; an swiveled connections between said operating member and the device to be controlled.`

2. Inv a control device of the class described, a tubular casing provided with a head having a plurality of transverse bores communicating with the interior of said casing; a cylindrical operating member provided with a helical groove, slidably mounted in said casing; spring pressed detent balls mounted in said bores, adapted t enga e said groove; an operating cable extending from said member to the device to be controlled; and a swivel connection between said member and said cable.

In testimony whereof, I aix my signature.
